Flask-Security is an extension for Flask that provides a robust framework for handling user authentication, authorization, and other security-related tasks in your web application. In this guide, we'll explore how to use Flask-Security to manage users, roles, and access control within your Flask application. By following this guide, you'll be able to enhance the security and user management features of your Flask applications.

Step 1: Setting Up Your Flask Application

Start by setting up your Flask application and installing the necessary extensions. Here's a sample directory structure:


Step 2: Integrating Flask-Security

Integrate Flask-Security into your Flask application by initializing it. Here's an example of how to do it:

from flask import Flask, render_template
from flask_sqlalchemy import SQLAlchemy
from flask_security import Security, SQLAlchemyUserDatastore
app = Flask(__name)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///myapp.db'
app.config['SECRET_KEY'] = 'your_secret_key' # Replace with your secret key
db = SQLAlchemy(app)
user_datastore = SQLAlchemyUserDatastore(db, User, Role)
security = Security(app, user_datastore)
def login():
return render_template('login.html')
if __name__ == '__main__':

Step 3: Creating User Management Templates

Create HTML templates for user management pages. Here's a basic structure for your login template (login.html):

<!DOCTYPE html>
<h2>Login Form</h2>
<form method="post" action="/login">
<label for="email">Email:</label>
<input type="text" id="email" name="email" required>
<label for="password">Password:</label>
<input type="password" id="password" name="password" required>
<button type="submit">Login</button>

Step 4: Running Your Application

Run your Flask application using the following command:


Access your web application in a browser, and you'll have a user login page with Flask-Security handling authentication and user management.


Flask-Security is a powerful extension for managing user authentication and access control in Flask applications. By following the steps in this guide, you can set up Flask-Security, create user management templates, and enhance the security and user management features of your Flask applications.
